Biggest Rhodium Disappointment? Phone reception.

Since I have gotten my Tilt 2 (ATT), I have not ever gotten good reception. I've flashed every ATT Radio, the newest radios (even non-att) and am running EnergyROM latest and can never maintain good phone reception. I always drop calls.
I know it's not my area, as I got great reception with my previous phone!
I feel like there is no way to get phone reception!!
Very disappointed in that
You guys experience the same problems?

no but theres no dead zones at all in houston.

yeah, i have nothing but good reception in my area (austin, texas and surrounding areas). Maybe you have a faulty antenna on your device. Have you called in At&t and tried to get a replacement? Head down to a Device Support center and talk to the guys there and they might change it on the spot for you, which i've had done many times with my original tilt and fuze.
Good luck.

Well, I changed my GSM Band to 1900+850 and flashed the latest radio and I seem to get better coverage.
One problem though (though it is minor): with these settings, it doesn't use HSDPA, only EDGE, which is slow lol
Any suggestions... please? Haha like maybe ghetto-rigging it with tinfoil? Ha I'm desperate

have you checked the coverage map of AT&T in your area? and also the material your house is built can also play a major role in signal, do you get more signal outside?

4G Reception

Hey guys. I live in an area that is in the mountains, so I thought there weren't any way that I could get 4G reception, until one day I was at Walmart and I was on 4G. When I was driving back I was on 4G until I got on campus. I was stuck on edge again and everyone knows how irritating that is. It seemed like overtime 4G was getting closer and closer until one day I got 4G in my room! This had excellent speeds, just like anyone would expect. Last night, I updated my ROM, which claimed that it boosted the signal on the phone, but yet I am stock with edge again. Can anyone explain this? My friend has a MyTouch 4G and he gets better reception than I do with my SII.

HTC uses more bars than Samsung does to represent the same amount of signal

I live in Montreal, middle of the city and I get terrible reception in my house, not to mention slow download speeds. I don't think its ROM based because i've been on 3 different roms with no change in signal. I think you're just gonna have to wait for your carrier to upgrade their antennas

I thought they were doing something with their antennas because of the 4G as well. Until it disappeared today. I don't know if they are working on it or something. I just want that 4G back.

Possible solution: (Just use this ROM, in my humble opinion it's the cleanest, fastest, prettiest, most well rounded ROM available for our phones. I've had excellent experience with it, particularly in the reception arena.)

My take on Galaxy Nexus problems (VZW)

I've had this phone now for less than a month. I know it's not a long time, but I think I've got a pretty good idea of how this phone performs. I have not rooted this phone, I am on 4.02 and PRL 15119.
1. The signal problem:
Coming from a Droid2, the first thing I noticed was one or no bars where I used to have full! I was losing data all the time, until I switched to CDMA only. My phone kept switching to LTE and back again, I spent more time in hand offs than connected!
I had the opportunity to have my Nexus, a TBolt, and a Maxx all in my basement together and did a few tests. All three phones had trouble holding LTE here when I was able to run a speed test, they all performed similarly, between 1 and 2 Mbps. When all three switched to CDMA, they displayed one more bar on and off than my Nexus, but showed similar pings and speeds.
I spend a lot of time in my basement and have never had troubles losing data (CDMA only) even though it displays 0-1 bars all the time.
Now, I do occasionally have problems with data, but it's nothing new to me. My Droid2 would show full signal and just not load a page or drop to 1x in locations known to be strong service.
I have not had this problem with the WiFi hand off back to cellular data. This phone switches faster than my Droid2 ever did. Like, by a lot. I work in no service building. Every morning I turn my WiFi on and just turn it off when I get in my car to go home. Usually I have cellular service before I can even turn off the WiFi.
I read a lot of reports where someones Nexus would be outperformed in a 4G speed test by another Verizon 4G device. Not the case here. My tests were constantly the same when comparing between the Nexus, TBolt, and Maxx.
I stopped in the Verizon store and two of the sales dudes had 4G phones, a Razr and another Galaxy Nexus. The Nexus guy was rooted on 4.04 and couldn't break 10Mbps while Razer guy and myself were fighting for 40Mbps.. Maybe there are some lemons out there
All in all, I may have gotten a good device (made in China, go figure), but I do not believe there is a real problem here. If this is your first android on Verizon, I can see where you'd think there are problems. Whenever I pick up my phone, I just ignore the bars and use it. It always works. Even in 3G, this phone loads pages WAY faster than my Droid2.
2. Battery life: I am not a real heavy user. There are times when I'll spend 20 minutes in the bathroom playing angry birds or reading threads, but that's about it. I got the Verizon extended battery before leaving the store with my new phone. This battery has 200mah more juice than the extended battery in my old Droid2.
I think this phone get's great stand by time, I got it to go 3 days off charger with a few calls and texts every day and a little bit of angry birds
On a whole, I'd have to say it get's as good or better life than my last phone.
3. Random reboots: I was constantly pulling my phone out of my pocket to find that it was off. I had gotten quite concerned after reading all the posts about crash reboots. It wasn't until I set the phone down while booting it up that I saw the screen shut off. I knew something wasn't right here and reproduced the shut down by smacking the phone in my palm while it was booting it up.
After looking closely, I noticed the battery would move up and down in its compartment. I solved this by taking some folded paper and taping it to the bottom edge of the battery. Pushing the battery up into the contacts on the phone. I also added some tape/paper to the top of the battery so the cover is pushing it down into the compartment.
Obviously I can't speak for everyone, but I haven't had a single crash/reboot. Just this battery connection problem.
4. Slow screen rotation: I have noticed this, it is VERY annoying when you first get the phone. Habit is to flip it landscape BEFORE launching the app you want to use. This is why you think it's so slow, because the home screen will not flip, it just refuses to. In any app, it flips just like you're used to. A non problem that I'm sure will get fixed.
5. Screen banding: I tried looking at the blank grey screen on any brightness, I could not get the bands I kept reading about. I guess I got lucky!
6. Overheating: I read this phone will try to use 2.4 and 5GHz spectrum's while on WiFi. The first thing I did was set it to 2.4 only and have not had any issues. I use WiFi 8 hours a day every day with out the phone getting hot. I also use the hot spot almost every night, as I don't have a land line internet at home. Never an issue, once again, to the touch this phone was not as hot as my Droid2.
I really like ICS and this phone seems like a keeper. I hope this inspires someone to go out and buy the Nexus!!

Over the weekend I went to the Verizon store to compare the vz nexus signal. Turns out every device with lte read -60 and then nexus -80. But there was one lg phone that displayed both signals at the same time, 1x and lte read -60 and -80. So I wonder does Verizon lte phones actually never show lte signal and always show cdma even when connected to lte?

Just earlier today I compared my Galaxy Nexus at -110 to my dad's Rezound at -80. Side by side at the exact same time. I'm sorry I didn't take a picture.
I'm unrooted stock 4.0.2 right now.

Silly question but did the salesman with the Nexus have LTE on?

How in the world could you go 3 days on a 2100mah? The most i can get is maybe a day or day and a half. Usually its under a day as i use my phone alot.

Lost the link but basically non ics phones show 3g signal instead of 4g or something like that. Its a different signal type that's why the gnex always shows less because its showing its actual signal

i honestly think its a hardware issue, but i have read all the threads and there is nothing concrete... my phone works perfect on 3g but i switch it to 4g and it just looses signal i could have 3 bars and then all of sudden it just looses all signal, it does not switch to 3g..im in a good 4g coverage area as well. im really angry and i dont want any other phone but the one i have . I hate blur so forget motorola

If they are not ICS devices, they do not show the LTE signal.

This was achieved over a weekend in a strong service area on cdma only. I was at a solid 3/⁴ bars the whole time. I was at a buddys house for a lan, so i was doing my surfing on the computer. I was doing most of my texting in google voice on my pc, so the only use the phone saw was calls and bathroom browsing lol.
Yes, the nexus measures signal differently and this is why it cant hold 4g, it thinks the signal is too weak and lets go before it should. If you had a vzw droid before and know where the strong 3g is, set it to cdma only and see how it performs compared to the old phone. If your getting data drops and dropped calls where you didnt before, then exchange your phone.
Ive read there is a way to force lte only, this would be the best test. But i cant remember how to do it.
Want to add, the ics keyboard is the best one ive ever used. Also, speaker volume on this phone is plenty loud. I have had problems with call quality when i have no bars. Just does not sound good and hard to unserstand people. When i have a bar or more, sounds great. Like theyre in the room.

Definitely lte. I am not sure what vzws theoretical max speed is on 3g, but in our area, max is about 1.7Mbps. I know theoretical is no where near 10Mbps.

Could the differences have been due to your radios? I'm on 4.0.4 with the new radios and I don't break 10Mpbs.
The speed is fast enough for me and I don't remember exactly the speeds I had on the earlier radios. I vaguely remember breaking 10Mpbs at times. I might reflash the older radios and do speed tests.

I'm happy to report I have zero problems with my VZW GNex since day 1

Now i didnt see these guys screens, i dont know what they were using for testing or what server they were connecting to. He told me hes never been able to break 10 megs. For all i know he rooted and flashed on day one. I cant imagine the members of xda would overlook something so obvious, but who knows. Give it a try eh? For reference all my mentions have been using the official speedtest.net app and chicago servers. Im tempted to root, but im waiting for 4.05 ota and have no idea how to do it. Ill get there eventually

I've found that LTE can vary wildly in speeds. You really need multiple tests with multiple phones at the same location/time.
That said, I saw a huge difference between FC05 and FA02. I found that the best combination for my phone was FC04 on the CDMA radio and FA02 on the LTE radio. It's a good 2mbits faster and much more stable. Signal in my house is borderline, so you really see the difference.

Thanks for the suggestion.
I flash the FC04/FA02 combo and in the spot near my house where I am disappointed, 4.5Mpbs down / 2.5 up, I got pretty much the same results. One difference I did notice is that the hybrid combo is slower to switch from 3G than FC05/FC05. I toggled LTE to force 4G connect.
I flashed back. Eager to see what 4.05 brings and also if the latest official IMM76K brings new radios.

[VZW] GN Weak radio bugging me

I don't know whether this is in my mind but since I have upgraded to JB, I seem to be getting weaker signal reception.
I live in a major LTE market and signal is usually pretty good outside on the street. Once I am a few feet from the street, say in a restaurant--even with big plate glass windows--or a house or a backyard, the signal drops to unusable.
This weakness was most graphic this past weekend when I found myself at a backyard BBQ. I couldn't get enough 3G signal to use the internet. Friends (running GB) with the Bionic or Thunderbolt, also on Verizon, standing right next to me were able to get a bar or two and reach the internet.
I'm not holding out hope that a radio release will miraculously fix our signal reception problems.

Wow! same problem here. When I flashed JB 4.1.1 I noticed a big difference in my reception. In rural areas The Galaxy Nexus has horrible reception anyways and We, I say we don't need to be getting weaker signals after flashing this really fast Jelly Bean rom...lol

The Verizon JB roms do not have any new radio's in them so I am not sure why you would be getting a worse signal then before. You should still get the same crappy signal you were getting on ICS.

Which radios are you running? FA02?
There's a thread on rootzwiki that has all of the historic radios for Verizon. Reading through it, some people have run a hybrid FA02/FC05 radio setup and say that's pretty good for them.
All I know is that I've got to figure something out. I went to a movie over the weekend and had my GNex in my pocket. I went through 50% battery during the movie because it couldn't find signal... and I wasn't really in a rural area.

I had generally bad service across the board 2G,3G,4G since getting the phone from Verizon. After flashing jellybean and keeping the stock FC04/FC05 radios cell service is pretty similar as expected. I cant really compalin given the area I live in but my old LG Env touch had stronger cell service. The most frustrating part was last week when I was with my friend in the hills of New Jersey where I could not get a single bar of service to even make a phone call and he was getting enough 3G on his iPhone to get on the internet. Rage.

Complete repository of all the radios:
http://goo.im/stock/toro/radios
I flashed FA02 from the command line and everything seemed to go okay but I still see FC04.
Hmmm...
Edit:
I redownloaded FA02 from the link I provided and the flash worked fine. (I had FA02 sitting on my drive from a previous download.)
I'll report back my experiences with the hybrid.

Are you trying an FA02/FC05 hybrid? I was tempted to do a flash-a-thon tomorrow night (busy tonight) and try each radio back to EK01/EK02 to see which seems best.

Nope its worse. I went froma -61dbm signal at home to -75. To make things worse, I lose data in rural areas now and my wifi sucks.

lte preferred network not working?

I live in Dallas tax and according to the coverage map lte is all over. When my preferred network settings are set to lte/ cdma it never connects to lte goes to 3g for a few minutes then disxonnexts. Switch my preferred network settings to cdma and 3g is always connected. Could this be a cyanogen issue or do most people deal with this? Any help would be appreciated.
Thanks

Sprint's marketing department figured it'd be better to show LTE coverage of completion. Unfortunately, your area is probably not covered yet, but will be once the city is completely upgraded.

So basically I need to leave it in CDMA preferred network mode to keep it connected?

LTE coverage would be a Sprint problem - the random disconnects are timeouts through eHRPD via Cyanogenmod RIL issues. It wont timeout on you on other ROMs, but if you place it onto CDMA only, you'll be fine.
Until Cyanogenmod fixes the problem, the random LoS (Loss of Service) issues will continue.

If you download and use Sensorly, it shows actual coverage, where actual users have picked up LTE coverage.

Anybody know of good ROMs that don't have this issue? My friend said aokp is good but he's on a different carrier, any thoughts?
Thanks

I was using AOKP and was having this same issue... assuming it's because they get a lot of their code from the CM repos.
I ended up trying out a few different TW ROMs and my signal strength was amazing with any of them. Currently I'm using FreeGS3 ( http://forum.xda-developers.com/showthread.php?t=1748818 ) and have no real issues.
The only thing that bugged me about the TW ROMs is some of the default apps like Email/Exchange, but I just replaced those with the APKs from AOKP and everything is fine.
If the signal issue gets fixed in CM/AOKP I would be more than willing to jump back, but the massive difference in signal strength is too much for me to not use a TW ROM.

All AOSP roms are based off CM10 github, so they're all going to have the issue. AOKP is a little dated now 11/10 build doesn't have LoS, but it doesn't connected to Ehrpd either. The issue is, once LTE connection is established, and you move outside an LTE area, you go LoS for a bit (some say 20 seconds, others say 5 minutes). But it wont lose signal until LTE is dropped.
EDIT: the cm10 timeouts were after the LJ7 blobs were implemented, which I believe were 11/11 and after.

This is also happening on stock jb.

thanks for the info, going to flash the tm rom when I get home.

Im in Dallas as well and its still being built out.
I get 3G at home, closer to down town. I get stable and steady 4G LTE at work, near Abrams and NorthWest HWY. In fact at my office on the 4th floor im on 4G LTE all day, ride the elevator down and by the time i get to my truck in the parking lot back to 3G. Drive a minute down the road and it might go back to 4GLTE again.
Luckily for me at my office on the 4th floor i get 4G LTE strong enough it holds the signal and isnt constantly switching.
The odd thing is a couple times a week my phone will switch to 4G LTE at my residence but when this happens i get no data on my device. I have to wait for it to go back to 3G to get data back. I think its a tower issue.

I'm having the same experience. LTE usuallys drops quickly. I get it in my apt and it is pretty fast. I live in Richardson. I experience LOS when I try to go from 4g to 3g. It drops the call everytime.

Well damn, hopefully they hurry and build out the network around dallas
